Researchers Measured the Amount of Plasma Carotenoids (In Micrograms Per

Multiple Choice

Researchers measured the amount of plasma carotenoids (in micrograms per milliliter) of male and female zebra finches. Here are the summary statistics from the study:
$$\begin{array} { | l | l | l | l | } \hline \text { Sex } & \boldsymbol { n } & \text { Mean } & \text { Standard Error } \\\hline \text { Males } & 50 & 31.77 & 1.85 \\\hline \text { Females } & 52 & 29.74 & 2.02 \\\hline\end{array}$$ Do male and female zebra finches differ in their plasma carotenoid levels? To answer this question, the researchers tested the following hypotheses:
?
H₀: ?_M=?_F versus ?_M??_F
What can we conclude at significance level 5%?

A) Reject the alternative hypothesis
B) Fail to reject the alternative hypothesis
C) Reject the null hypothesis
D) Fail to reject the null hypothesis
